Log:
Add separate convert_costs for signed vs. unsigned

[Branch only patch -- not intended for trunk in its current state]

This patch makes convert_cost record separate costs for sign and
zero extension, in case one is more expensive than the other.
This probably doesn't make a difference any more.
